Irish rap trio Kneecap posted a lengthy statement online Monday after their messages critiquing Israel at Coachella ignited controversy.

The Irish rap group Kneecap denounced Hamas and Hezbollah after Micheál Martin, the Irish prime minister, called on them to “urgently clarify” their stances. The group is from Belfast, the capital of Northern Ireland in the United Kingdom, and U.K. police have also announced that they are investigating the group.
